To all 1.071.011? it may concern.-

Be it known that I, GEORGE W. MACKENZIE, a citizen of the United States,residing at Beaver, in the county of Beaver and Stateof Pennsylvania,have invented certain new and useful Improvements in (Join ControlledVending Apparatus, of which the following is a specification, referencebeing had therein to the accompanying drawings, forming part of thisspecification, in which-- Figure 1 is a face view in elevation, partlybroken away, of my improved eoin-controlled vending-machine. Fig. 2 is aside View thereof. Fig. 3 is a horizontal sectional View on the line IIIIII of Fig. 1. Fig. 4: is a perspective detail view, on an enlargedscale, showing the push-bar and its connected mechanism and thecoin-controlled locking-arm, the parts being in their normal position.Fig. 5 is a partial vertical sectional view indicated by the line V V ofFig. 3, the rotating carrying-wheel having been removed. Fig. 6 is apartial sectional viewillustrating the action of the coin to unlock thelocking-arm, so as to release the puslrbar. Fig. 7 is a similar viewshowing the push-bar depressed, having turned the carrying-wheel almostone space and raised the locking-arm, releasing the coin. Fig. 8 is adetail view of the inner end of the push-bar and its shifting devices,showing the parts in position immediately before the termination of theoutward travel, the inner end of the locking-arm having dropped down infront of the bar. Fig. 9 is a similar view showing the bar havingcompleted its outward travel and finishing the shifting operation, so asto complete the period of movement of the carrying-whcel. Fig. 10 is adetail view of the back portion of the apparatus, showing the locking-arm and the counterweighting arrestingarm. Fig. 11 is a detail viewshowing a modified form of carrier.

My invention relates to automatic vending devices wherein a rotatingcarrier is adapted to hold or contain the articles to be vended and isintermittently operated by a coin-con- Serial No. 125,646. on) model.)

trolled push-bar, so as to exposea special article, quantity, or number0t articles at each operation.

Referring to the drawings, 2 represents the ease of the apparatus, uponan inner wall or supports 3 bearing 4, upon which 1s rotatably mountedof which is mounted a stud or 7 of the case is provided with an opening8 3 of suitable area and form to permit the removal of the article, withwhich opening the pockets 6 are adapted to intermittently andsuccessively come into register. The front 7 may be hinged to the maincase and may conveniently be made of plate-glass or be provided with apane of glass adapted to expose the contents of the carrier or a portionof them immediately in advance of the opening 8, so as to indicate thecontents or the condition of the apparatus whether charged or empty.

Extending baekwardly from the carrier 5 concentric with its center is aseries of pins or abutments 9, corresponding to the pockets 6, asindicated in Fig. 1. Slidingly mounted in the interior of the casein anysuitable support is a push-bar 10, the stem 11 of which extendsoutwardly through the side of the case in a suitable bearing and isprovided with a push-button 12, the push bar andv button being normallyretracted by a spring 13 of any suitable form, secured to the push-barand to the interior of the case. Pivotally mounted at 14 on the push-baris a shifting finger 15, I

having a tapered face 16, adapted to engage one of the pins 9 in theforward movement of the puslrbar, forcing it up and rotating the carrierin the direction of the arrow in Fig. 5, in which figure the pins 9 areindicated as standing in front of the shifting apparatus. The back endof the shifting finger 15 is slotted, as at 17, and is engaged by a pin18, limiting the downward travel of its point, the

back end being normally held raised, as in Fig. 5, by a counterweightedlever 19, pivoted to the push-bar at 20.

In front of the finger is a lug 21, provided with a cam-face 22, adaptedto engage the partially-shifted pin 9 on backward movement of the bar,moving the pin up and completing the operation.

Pivoted at 23 is a locking-arm 24:, the inner end 25 of which is bentaround and adapted to engage the front end of the push-bar, so as tolock the push-bar against inward travel, the outer end of thelocking-arm extending through a vertical slot 26 into the path of a coinadapted to travel downwardly through coin-slot 27. The outer end of thelockingarm is normally held raised in the slot by reason of the slightlygreater weight of the inner end, which extends through a slot 28. or isotherwise suitably arranged, so as to stand immediately in front of thepush-bar, the locking-arm being delicately balanced, so as to besensitive to the gravitating action of the coin. 29 is an arresting-armpivoted at 30 and having an upwardly -extending extremity 31, adapted toarrest the downward travel of the inner end of the locking-arm whendepressed by the weight of the coin, thus raising the inner end 25sufficiently far to unlock the push-bar, as in Fig. 6.

The arresting-arm has a counterweighting extension 32, adapted to raisethe extremity 31, its upward movement being limited by a pin or abutment33.

A coin having been dropped from the exterior of the case in the slot 27,its weight depresses the outer end of the locking-arm, raising the innerend, when the push-bar may be pushed in, whereupon the point of thefinger 15 engages one of the pins or abutments 9, causing it to rideupwardly on cam-face 16, and upon releasing pressure from the push-barthe spring 13 will retract it and the cam-face 22 of lug 21 willcomplete the movement of the pin, thus producing an intermittentrotation of the carrier equivalent to the pitch or space between thepins and moving the pockets 6 one space. The forward or inner end of thepush-bar is provided with an inclined camface 34:, which engages the end25 of the locking-arm, tilting it upwardly and depressing its outer end,which bears down against the terminal 31 of the arresting-arm. thusreleasing the coin, as in Fig. 7, which then drops down through the slotinto a receptacle 35 in the interior of the case. Upon releasing thepush-bar the locking-arm resumes its normal position in front of thebar, looking it against further movement until released by the insertionof another coin.

As will be understood, the locking-arm is balanced, and its proportions,as well as those of the coin-slot, are adjusted to be operated tendingcylindrical openings in which a plurality of cigars or cigarettes may beinserted, all of which may be exposed at one time, as illustrated inFig. 11. The carrier may also be provided with any suitable holdingdevice as, for instance, pinsupon which stamps or other articles may beaffixed, and various other adaptations of the device may be made to suitdifferent requirements of use.

It will be understood that the front door or partition or otherremovable closure is to be provided with a suitable look, so as toprevent tampering with the machine or access to its interior withoutunlocking. Other changes or variations may be made in the design,proportions, or other details by the skilled mechanic without departingfrom the invention, and all such are to be considered as within thescope of the following claims.

WVhat I claim is- 1. The combination with the push-bar of avending-machine provided at its forward end with an abutting end and abackwardly-sloping inclined cam; of a pivoted locking-lever having aterminal adapted to engage the abutting end and to be engaged by theinclined cam of the push-bar, and a pivoted counterweightlever adapted,to be depressed by the other end of said locking-lever upon inwardmovement of the push-bar, and to be raised by said counterweight-leverupon return movement of the push-bar, substantially as set forth.

2. The combination with the push-bar of a vending-machine provided atits forward end with an abutting end and a backwardly-sloping inclinedcam; of a pivoted locking-lever having a terminal adapted to engage theabutting end and to be engaged by the inclined cam of the push-bar, acoin-chute so located as to receive the other end of said locking-lever,and a pivoted counterweight-lever adapted to be depressed by the saidother end of the locking-lever upon inward movement of the pushbar, andsaid end of the.locking-lever to be raised by said counterweight-leverupon return movement of the push-bar, substantially as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.

GEORGE W. MACKENZIE.
